The accounting matters assessed included, but were not limited to, allowance for doubtful accounts, the carrying value of goodwill and other long-lived tangible and intangible assets, the potential impact to earnings of unrealized losses on investments and valuation allowances for tax assets. While the assessments resulted in no material impacts to the consolidated financial statements as of and for the year ended June 28, 2020, the Company believes the full impact of the outbreak remains uncertain and will continue to assess if ongoing developments related to the outbreak may cause future material impacts to its consolidated financial statements.</span></div>
